Cyclodextrin glycosyl transferase
WebThe enzyme cyclodextrin glycosyltransferase is closely related to α-amylases but has the unique ability to produce cyclodextrins (circular α(1→4)-linked glucoses) from starch. To characterize this specificity we determined a 1.8-Å structure of an E257Q/D229N mutant cyclodextrin glycosyltransferase in complex with its product γ-cyclodextrin, WebCyclodextrins (CDs) are carrier molecules produced by cyclization of α-1,4-glucans by Cyclodextrin Glycosyl Transferase (CGTase). These torus shaped molecules have …
